Context: The origin of money is something to do with representational thinking. Representational thinking is the real leap, where somebody says ‘hey I can draw this shape on the cave wall and it is, in some way, the bison we saw at the meadow. These lines are the bison. That of course lead to language – this squiggle is, of course, a tree, or something. Is the tree. Money is code for the whole of life – you can bind in everything that is contained within life for money, money is a certain amount of sex, a certain amount of shelter, a certain amount of sustenance. … Money is the code for the entire world. Money is the world, the world in the sense I was talking about earlier, our abstract ideas about the world. Money is a perfect symbol for all that, and if you don’t believe in it, and you set a match to it, it’s just firewood – it doesn’t mean anything anymore.
